Inkbox formulations contain ingredients you may not have put on your skin before. As a result, there's a small risk of allergic reaction upon application (or of sensitization through repeated use).
If a reaction takes place, it's usually a mild case of contact dermatitis (red or inflamed skin as a result of irritation). Once the tattoo fades away, there will be a light red outline of the design on the skin. The itchiness/irritation should subside in a few days. If symptoms persist, contact a doctor!
The health and safety of Inkbox customers is our priority. If you're experiencing any physical discomfort or irritability, we'd like to hear from you. Please send us an email at firstname.lastname@example.org.
